From the inner wall of the aluminum tube, since the refrigerant does not contain water, the inner wall of the copper aluminum connecting tube will not be corroded. The lower the heat transfer efficiency of the connecting pipeline between the indoor unit and the outdoor unit of the air conditioner, the more energy will be saved, or the better the insulation effect, the more power will be saved. Excellent bending performance, easy to install and move.

Aluminum tube is a kind of nonferrous metal tube, which refers to the metal tubular material extruded from pure aluminum or aluminum alloy to be hollow along its longitudinal full length. There can be one or more closed through holes with uniform wall thickness and cross section, which are delivered in straight line or roll form. It is widely used in automobile, ship, aerospace, aviation, electrical appliances, agriculture, electromechanical, household and other industries.
